Benefits of technology

[0027]Other advantages of the system may include complete data protection to small and mid-sized companies by delivering each of the four components of data protection: online backup, disaster recovery, offsite data storage, and compliance. Online backup is a simple and automated way to backup the company's servers and laptops and is the first piece of the data protection puzzle. With the system, incremental backups are completed quickly thanks to de-duplication and multi-threaded data transfer over https. Disaster recovery is an impo

Problems solved by technology

Performance is greatly increased, but in case of losing a local storage, the remote storage is not guaranteed to have the current copy of data and most recent data may be lost.

Example

[0054]FIG. 1B shows a second embodiment of the disaster recovery and backup system. In this system a plurality of data centers are provided to provide high availability. Each data center has routers 132 that communicate to load proxy machines 134 to distribute incoming requests to a plurality of application servers 136. In one embodiment, the routing infrastructure is based on 10 G technology and is redundant at every level. In this embodiment, Load Proxy servers 134 receive incoming requests, validate the credentials in the request against LDAP, and route them to the application server that hosts the volume. Proxies are deployed as HA pairs. HTML based applications can be hosted here to provide seamless access for the user using a web browser.

[0055]The servers 136 communicated with a clustered storage array 138. The application servers 136 handle the bulk of the system load by providing a file system interface to the underlying data storage system 138. Most file system functions ar...

Abstract

A method for backing up a client data set on a computer by generating a manifest of the client data set and storing the manifest on a remote server along with a server data set corresponding to the client data set; taking a snapshot of the server manifest and data set; and comparing the manifest to the remote server data set and synchronizing the client dataset if a difference is detected.

Description

FIELD OF INVENTION[0001]The invention relates to systems and methods for disaster recovery and / or maintaining back up files for servers on a computer network.BACKGROUND OF THE INVENTION[0002]Asynchronous replication relates to a technology used in server and network storage. Once data has been written to the primary storage site, new writes to that site can be accepted, without having to wait for the secondary or remote storage site to also finish its writes. The remote storage is updated, but probably with a small lag. Performance is greatly increased, but in case of losing a local storage, the remote storage is not guaranteed to have the current copy of data and most recent data may be lost. Thus, the downside to asynchronous replication is the possibility of data loss if the primary site should happen to fail before the data has been written to the secondary site.[0003]As companies today become more accustomed to storing important company information on their data network, the va...
